Description

Technical Field

[0001] The utility model belongs to the technical field of self-baking electrodes for submerged arc furnaces, in particular to an unmanned quantitative electrode paste adding device for submerged arc furnaces. Background Art

[0002] Self-baking electrodes are electrometallurgical devices used during the smelting process in a submerged arc furnace. Arc heat at the end of the fired electrode column and the resistance heat of the charge or slag convert electrical energy into thermal energy, reducing alloying elements from ores or oxides. In addition to smelting ferroalloy products, submerged arc furnaces also perform a crucial task: firing the electrodes. The quality of electrode firing determines the proper operation of the furnace. Self-baking electrodes primarily consist of an electrode shell, conductive ribs, and fired electrode paste. Electrode paste is added to the shell from above the electrode, melting and sintering as the temperature rises. During the electrode paste sintering process, a key parameter to control is the firing zone. This is where the electrode paste transitions from liquid to solid and begins to conduct electricity. An improper firing zone can lead to hard or soft electrode fractures, as well as paste flow. Electrode failures are a major factor impacting normal production. Therefore, key factors influencing electrode firing quality include maintaining a stable paste column height and the method of adding paste to prevent overhanging paste.

[0003] In the past, electrode paste was mostly added manually. Workers lifted the electrode paste to the electrode paste adding platform through material hoisting, used ton bags to hold the electrode paste and transported them to the opening above the electrode cylinder. After unpacking the bag, the electrode paste was poured into the electrode cylinder. Due to uncontrollable factors in manual paste adding, there would be too much or too little paste added, resulting in a large height difference of the paste column. Manual paste addition and instantaneous dumping of electrode paste are prone to cause paste hanging accidents. Manual paste adding is labor-intensive. Because the electrode cylinder is energized when it is in working state, electric shock accidents are likely to occur if there are any operational errors.

[0004] To this end, we provide an unmanned quantitative electrode paste adding device for a submerged arc furnace to solve the above problems. Utility Model Content
